I'm still running it through xm-test to check for regression.  I see 9 failures
with this on i386 and x86_64 with changeset 7793, so any other
testing/explanations would be helpful.  Here are the failures that I see:

anball          Device is not actually attached to domU
anball  FAIL: 05_block_attach_and_dettach_device_repeatedly_pos
anball          Failed to attach block device /proc/partitions does not show 
that!
